Arduino Doctor Who Countdown timer prop - HELP!!!

[jorj]

One thing about the green backpack display in my case is that it is a bit bright in low light.
I've been trying to figure out how to dim the display within the code.

Adafruit indicates that it can be done with a small amount of code (brightness setting), but I can't figure out where and how to use it.

.

If you're using the Adafruit_LED_Backpack code something like this:

Adafruit_7segment matrix = Adafruit_7segment();

Then you probably just have to add this to setup():

matrix.setBrightness(15);

... where "15" is a number from 0 (dimmest) to 15 (brightest).

Thanks jorj,

That worked !
Putting that small amount of code in the

setup() {
matrix.setBrightness(0);
} // did the job.

Adafruit gave this bit of information:
<snip>
There are also a few small routines that are special to the backpack:

• setBrightness(brightness)- will let you change the overall brightness of the entire display. 0 is least bright, 15 is brightest and is what is initialized by the display when you start.

They didn't give the matrix. and ; part. ......I guess I should of known that and figured it out for myself.

Thanks again for the corrected information ..
